To reduce weight, some display modules use low-density aluminum alloy backplates instead of stainless steel backplates. However, aluminum alloy backplates are relatively weak and are prone to deformation during static or dynamic pressure testing, which can lead to display defects in the display panel.

[0006] In some embodiments, the second connection structure includes a connecting portion and a first hook. The first hook is connected to the back plate through the connecting portion and is connected to the end of the connecting portion away from the back plate in a second direction. The end of the first hook away from the connecting portion in a first direction has a first limiting wall. The end of the first hook close to the back plate in a second direction has a second limiting wall. The first limiting portion is an elastic arm extending in a second direction, and the second limiting portion is a second hook. The elastic arm is connected between the support plate and the second hook. The second hook engages with the first hook and is located between the first hook and the back plate in a second direction.

[0007] In some embodiments, the connecting part, the first hook, and the back plate are integrally formed; the elastic arm, the second hook, and the support plate are integrally formed.

[0008] In some embodiments, the second connection structure includes a connector, the connector having a connecting hole extending in a second direction, the connecting hole penetrating the connector in the second direction; the hole wall of the connecting hole is a first limiting wall, and the end of the connector away from the support plate in the second direction has a second limiting wall; the first connection structure includes a screw, the screw passing through the connecting hole and connected to the support plate, the shank of the screw being a first limiting portion, the head of the screw being a second limiting portion, and the head of the screw abutting against the second limiting wall.

[0009] In some embodiments, each connection hole is located on one side of the back plate in a direction perpendicular to the second direction.

[0010] In some embodiments, the housing further includes a support frame connected to the edge of the support plate. The support frame is located on the periphery of the back plate. The end of the support frame away from the support plate along the second direction is provided with a plurality of notches.

[0022] An embodiment of the first aspect of this application provides a display module that can be used in devices such as laptops and mobile phones.

[0023] Please refer to Figure 2and Figure 3 The display module 100 of this application embodiment includes a housing 10, a back plate 20, and a display panel 60. The housing 10 has a support plate 11, and the support plate 11 is provided with at least two first connecting structures 30 spaced apart along a first direction X. The back plate 20 is disposed on one side of the support plate 11 along a second direction Z, the second direction Z being perpendicular to the first direction X; the back plate 20 is provided with at least two second connecting structures 40 spaced apart along the first direction X, and the plurality of second connecting structures 40 are respectively connected to the plurality of first connecting structures 30 in a one-to-one correspondence; the at least two first connecting structures 30 are used to abut and constrain the corresponding second connecting structures 40 in the first direction X. The display panel 60 is connected to the back plate 20.

[0024] The outer shell 10 can support and protect the back plate 20, and the support plate 11 is the plate with the largest area on the outer shell 10. Two or more first connection structures 30 can be provided on the support plate 11, and at least two of the first connection structures 30 are spaced apart along the first direction X.

[0025] The second direction Z is the arrangement direction of the back plate 20 and the support plate 11, and the second direction Z is perpendicular to the display panel 60. Two or more second connection structures 40 can be provided on the back plate 20, and each second connection structure 40 is connected to a first connection structure 30. The back plate 20 is connected to the support plate 11 through the first connection structure 30 and the second connection structure 40.

[0026] Two second connecting structures 40 are spaced apart along the first direction X and are connected one-to-one with two first connecting structures 30 spaced apart along the first direction X. The two spaced first connecting structures 30 respectively abut against the two spaced second connecting structures 40 along the first direction X and restrict the movement of the two second connecting structures 40 along the first direction X.

[0027] Optionally, in the first direction X, two first connecting structures 30 spaced apart along the first direction X can be disposed between two spaced second connecting structures 40 connected thereto. The two spaced first connecting structures 30 abut against the second connecting structures 40 connected thereto in opposite directions, restricting the two second connecting structures 40 from approaching each other. Optionally, the first connecting structure 30 can also be an annular member sleeved on the second connecting structure 40, and the first connecting structure 30 can abut against the second connecting structure 40 connected thereto in both the positive and negative directions of the first direction X.

[0028] Optionally, the display panel 60 can be a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like.

[0029] Please refer to Figure 1 During static or dynamic pressure testing, pressure is applied to the support plate 11 along the second direction Z. The support plate 11 exerts pressure F on the back plate 20, causing the back plate 20 to deform. Excessive deformation of the back plate 20 can compress the display panel 60. The display panel 60 has weak bending resistance and is easily damaged after being compressed. When the display panel 60 is compressed by the back plate 20, it may exhibit defects such as red and blue spots or bright spots.

[0030] When the back plate 20 is pressed by the support plate 11, the portion of the back plate 20 between the two second connecting structures 40 spaced apart along the first direction X is pressed by the support plate 11. This portion of the back plate 20 (the portion of the back plate 20 refers to a part of the back plate 20) may deform along the second direction Z towards the display panel 60. The surrounding portion of the back plate 20 moves closer to the pressed portion of the back plate 20, and the two second connecting structures 40 connected to the back plate 20 spaced apart along the first direction X move closer to each other. The two spaced first connecting structures 30 abut against the two second connecting structures 40, restricting the two second connecting structures 40 from moving closer to each other, thereby preventing the deformation of the pressed portion of the back plate 20. Please refer to... Figure 4 When the back plate 20 is subjected to pressure F, the resultant force F2 of the supporting force F1 of the multiple first connecting structures 30 on their corresponding second connecting structures 40 is opposite to the direction of the pressure F on the back plate 20, thereby reducing the deformation of the back plate 20.

[0031] The beneficial effects of this embodiment are as follows: at least two first connecting structures 30 spaced apart along the first direction X are connected to the support plate 11, and at least two second connecting structures 40 spaced apart along the first direction X are connected to the back plate 20. These two first connecting structures 30 abut against and constrain the two second connecting structures 40 along the first direction X. When the portion of the back plate 20 between the two second connecting structures 40 spaced apart along the first direction X is compressed by the support plate 11, the back plate 20 may bend, causing the two second connecting structures 40 to move closer to each other along the first direction X. At this time, the two first connecting structures 30 can limit the two second connecting structures 40 from moving closer to each other along the first direction X. The abutting force of the multiple first connecting structures 30 against the second connecting structures 40 can reduce the deformation of the back plate 20, preventing excessive deformation of the back plate 20 from damaging the display panel 60, thus enabling the display panel 60 to display images normally. In static pressure tests, dynamic pressure tests, and when the user carries the display module 100 in a backpack, the first connecting structures 30 and the second connecting structures 40 can prevent the display panel 60 from being damaged after the back plate 20 deforms. The embodiments of this application can solve the technical problem that deformation of the back plate 20 leads to poor display of the display panel 60.

[0032] In some embodiments, the display module 100 further includes a backlight assembly 50, which is connected to the back panel 20 and is used to illuminate the display panel 60.

[0033] Optionally, the backlight assembly 50 includes a light source, a light guide plate, a reflective sheet, and an optical film, which work together to provide uniform backlight illumination for the display panel 60.

[0034] Optionally, the backlight assembly 50 can be located between the display panel 60 and the back panel 20 along the second direction Z. Optionally, the light source and light guide plate in the backlight assembly 50 can also be disposed on one side of the display panel 60 along the first direction X, which can reduce the thickness of the display module 100.

[0035] Excessive deformation of the backplate 20 can compress the backlight assembly 50. The film and light guide plate in the backlight assembly 50 are typically made of flexible materials with weak compressive strength, making them prone to damage when compressed. This can lead to defects such as red and blue spots and bright spots on the display panel 60. When the portion of the backplate 20 between the two second connecting structures 40 spaced along the first direction X is compressed by the support plate 11, the backplate 20 may bend, causing the two second connecting structures 40 to move closer together along the first direction X. At this time, the two first connecting structures 30 can limit the two second connecting structures 40 from moving closer together along the first direction X. The supporting force of the multiple first connecting structures 30 on the second connecting structures 40 can reduce the deformation of the backplate 20, preventing excessive deformation that could damage the backlight assembly 50 and allowing the display panel 60 to display the image normally.

[0036] In some embodiments, please refer to Figure 2 and Figure 3 The second connecting structure 40 has a first limiting wall 41 and a second limiting wall 42. The first limiting wall 41 intersects with the first direction X, and the second limiting wall 42 intersects with the second direction Z.

[0037] The first connecting structure 30 includes a first limiting part 31 and a second limiting part 32. The first limiting part 31 is connected to the support plate 11, and the second limiting part 32 is connected to the end of the first limiting part 31 away from the support plate 11. At least two first limiting parts 31 are used to abut against and constrain the corresponding first limiting wall 41 in the first direction X; the second limiting part 32 is used to abut against and constrain the corresponding second limiting wall 42 in the second direction Z.

[0038] The first limiting wall 41 and the second limiting wall 42 are the two outer walls of the second connecting structure 40.

[0039] The second limiting part 32 is connected to the support plate 11 through the first limiting part 31.

[0040] At least two spaced first limiting portions 31 are used to abut against and constrain the two spaced first limiting walls 41 in the first direction X, thereby preventing the two spaced first limiting walls 41 along the first direction X from approaching each other. The two spaced first limiting portions 31 are respectively located on two spaced first connecting structures 30 along the first direction X, and the two spaced first limiting walls 41 are respectively located on two spaced second connecting structures 40 along the first direction X. Optionally, at least two spaced first limiting portions 31 are located between the two spaced first limiting walls 41.

[0041] Two spaced first connecting structures 30 are restricted from approaching each other by first limiting portions 31. When the portion of the back plate 20 between the two spaced second connecting structures 40 is pressed by the support plate 11, the resultant force of the two first limiting portions 31 of the two first connecting structures 30 against the two first limiting walls 41 of the two second connecting structures 40 is opposite to the direction of the pressure on the back plate 20, which can reduce the deformation of the back plate 20.

[0042] Optionally, the first limiting wall 41 can be perpendicular to the first direction X, and the first connecting part 43 can be provided with an outer wall that abuts against and is parallel to the first limiting wall 41, so that the abutting force of the first connecting part 43 against the first limiting wall 41 can be evenly distributed on the first limiting wall 41.

[0043] Optionally, the first connecting part 43 can be a rod-shaped member, plate-shaped member, etc., parallel to the first limiting wall 41.

[0044] The second limiting part 32 is used to abut and constrain the second limiting wall 42 in the second direction Z. The second limiting part 32 is at least partially located on the side of the second limiting wall 42 close to the display panel 60 in the second direction Z, and restricts the second limiting wall 42 from approaching the display panel 60 in the second direction Z. When the back plate 20 is subjected to pressure in the second direction Z applied by the support plate 11, the abutting force of the second limiting part 32 on the second limiting wall 42 is opposite to the pressure direction of the support plate 11 on the back plate 20, and the second limiting part 32 can further reduce the amount of deformation generated by the back plate 20.

[0045] Optionally, the second limiting wall 42 can be perpendicular to the second direction Z, and the second connecting part 43 can be provided with an outer wall that abuts against and is parallel to the second limiting wall 42. The abutting force of the second connecting part 43 against the second limiting wall 42 can be evenly distributed on the first limiting wall 41.

[0046] Optionally, the second connecting part 43 can be a rod-shaped member, plate-shaped member, or the like, parallel to the second limiting wall 42.

[0047] The beneficial effects of this application embodiment are as follows: the two spaced first connecting structures 30 abut against and constrain the first limiting walls 41 of the two second connecting structures 40 along the first direction X through the first limiting part 31, and restrict the two spaced second connecting structures 40 along the first direction X from approaching each other; when the portion of the back plate 20 between the two spaced second connecting structures 40 along the first direction X is squeezed by the support plate 11, the resultant force of the two first limiting parts 31 of the two first connecting structures 30 against the two first limiting walls 41 of the two second connecting structures 40 is opposite to the direction of the pressure on the back plate 20, which can reduce the deformation of the back plate 20. The second limiting part 32 is used to prevent the second limiting wall 42 from approaching the display panel 60 along the second direction Z. When the portion of the back plate 20 between the two spaced second connecting structures 40 along the first direction X is squeezed by the support plate 11, the holding force of the second limiting part 32 against the second limiting wall 42 is opposite to the direction of the pressure of the support plate 11 on the back plate 20, which can further reduce the deformation of the back plate 20.

[0048] In some embodiments, please refer to Figure 2 and Figure 3 The second connection structure 40 includes a connecting part 43 and a first hook 45. The first hook 45 is connected to the back plate 20 through the connecting part 43. The first hook 45 is connected to the end of the connecting part 43 away from the back plate 20 along the second direction Z. The end of the first hook 45 away from the connecting part 43 along the first direction X has a first limiting wall 41. The end of the first hook 45 close to the back plate 20 along the second direction Z has a second limiting wall 42.

[0049] The first limiting part 31 is an elastic arm extending along the second direction Z, and the second limiting part 32 is a second hook. The elastic arm is connected between the support plate 11 and the second hook. The second hook is engaged with the first hook 45. The second hook is located between the first hook 45 and the back plate 20 along the second direction Z.

[0050] The first hook 45 is connected to the back plate 20 via the connecting part 43, that is, the connecting part 43 is connected to the back plate 20. The first hook 45 is connected to the end of the connecting part 43 that is away from the back plate 20 along the second direction Z, so the first hook 45 is spaced apart from the back plate 20 along the second direction Z. Optionally, the connecting part 43 can be a rod-shaped member, plate-shaped member, etc. extending along the second direction Z.

[0051] The first hook 45 has a first limiting wall 41 at one end opposite to the connecting part 43 along the first direction X. That is, one end of the first hook 45 along the first direction X is connected to the connecting part 43, and the other end of the first hook 45 along the first direction X extends to the outside of the connecting part 43 and has the first limiting wall 41.

[0052] The second connecting structure 40 and the first connecting structure 30 are engaged by the first hook 45 and the second hook. The elastic arm has a certain elastic deformation capability. When connecting the support plate 11 and the back plate 20, the elastic arm will first deform, causing the second hook to move closer to the back plate 20 along the second direction Z while also moving along the first direction X. After the second hook passes the first hook 45, the elastic arm rebounds, causing the second hook to engage in the space between the first hook 45 and the back plate 20. At this time, the second hook and the first hook 45 are engaged, and the elastic arm abuts against the first limiting wall 41, while the second hook abuts against the second limiting wall 42, thus achieving a stable connection between the support plate 11 and the back plate 20.

[0053] The beneficial effects of this embodiment are as follows: the support plate 11 is engaged with the first hook 45 of the second connecting structure 40 on the back plate 20 via elastic arms and the second hook. No additional connecting tools are required when connecting the support plate 11 and the back plate 20, allowing for rapid connection and higher manufacturing efficiency of the display module 100. When the back plate 20 is subjected to pressure from the support plate 11, the combined force of the elastic arms of the multiple first connecting structures 30 resisting the first hook 45 and the second hook resisting the first hook 45 can prevent the support plate 11 from bending and deforming, thus reducing the amount of deformation of the back plate 20.

[0054] In some embodiments, please refer to Figure 2 and Figure 3 The connecting part 43, the first hook 45 and the back plate 20 are integrally formed. The overall production efficiency of the back plate 20 and the second connecting structure 40 is high, and the second connecting structure 40 is firmly connected to the back plate 20.

[0055] Optionally, the connecting part 43 and the first hook 45 can be formed by stamping and bending a part of the back plate 20.

[0056] In some embodiments, please refer to Figure 2 and Figure 3 The elastic arm, the second hook, and the support plate 11 are integrally formed. The support plate 11 and the first connecting structure 30 have high overall production efficiency, and the first connecting structure 30 and the support plate 11 are firmly connected.

[0057] Optionally, the elastic arm, the second hook, and the support plate 11 can be integrally injection molded.

[0058] In some embodiments, please refer to Figure 7 and Figure 8 The second connection structure 40 includes a connector, on which a connection hole 44 extending along the second direction Z is provided, and the connection hole 44 penetrates the connector along the second direction Z; the hole wall of the connection hole 44 is a first limiting wall 41, and the end of the connector away from the support plate 11 along the second direction Z has a second limiting wall 42.

[0059] The first connecting structure 30 includes a screw that passes through a connecting hole 44 and is connected to the support plate 11. The shank of the screw is a first limiting part 31, the head of the screw is a second limiting part 32, and the head of the screw abuts against the second limiting wall 42.

[0060] If the shank of the screw is the first limiting portion 31, then the shank of the screw abuts against and constrains the wall of the connecting hole 44 to move along the first direction X. Optionally, the shank of the screw abuts against the wall of the connecting hole 44 radially. For example, the connecting hole 44 is a threaded hole that is threadedly connected to the shank of the screw.

[0061] The connecting hole 44 passes through the connector along the second direction Z, and the shank of the screw passes through the connecting hole 44 and is connected to the support plate 11. That is, the head of the screw is located on the side of the connector away from the support plate 11 along the second direction Z. The head of the screw can restrict the connector from moving away from the support plate 11 along the second direction Z.

[0062] Optionally, the first connecting structure 30 may be a screw. Optionally, the first connecting structure 30 may also include other components besides screws.

[0063] Optionally, the second connection structure 40 may be a connector. Optionally, the second connection structure 40 may also include other components besides the connector.

[0064] The beneficial effects of this embodiment are as follows: the support plate 11 can be securely connected to the back plate 20 by screws and connectors, and the screws are easy to install and remove, facilitating the disassembly and maintenance of the support plate 11 and the back plate 20. When the back plate 20 is subjected to pressure from the support plate 11, the combined force of the bearing force of the two screws spaced X along the first direction on the wall of the connecting hole 44 and the bearing force of the screw head on the connector is opposite to the pressure direction of the support plate 11 on the back plate 20, which can reduce the deformation of the back plate 20.

[0065] In some embodiments, please refer to Figure 7 and Figure 8 The housing 10 also includes a plurality of support blocks fixed on the support plate 11. In the second direction Z, the support blocks are located between the support plate 11 and the connector, and the screws are threadedly connected to the support blocks.

[0066] In some embodiments, please refer to Figure 7 and Figure 8 In a direction perpendicular to the second direction Z, each connection hole 44 is located on one side of the back plate 20.

[0067] The direction perpendicular to the second direction Z includes the first direction X, and also includes multiple directions intersecting the first direction X. At least two connecting holes 44 are distributed on both sides of the back plate 20 along the first direction X. Multiple connecting holes 44 are distributed circumferentially along the back plate 20; the circumferential direction of the back plate 20 is perpendicular to the second direction Z. Optionally, in the multiple directions perpendicular to the second direction Z, the multiple connecting holes 44 can be respectively disposed on different sides of the back plate 20. For example, four connectors are provided, with two connecting holes 44 respectively disposed on both sides of the back plate 20 along its width direction, and the other two connecting holes 44 respectively disposed on both sides of the back plate 20 along its length direction.

[0068] In the direction perpendicular to the second direction Z, the connecting holes 44 are all located on one side of the back plate 20. The connecting plate where the connecting holes 44 are located and the screws in the connecting holes 44 are set on one side of the back plate 20. The connecting plate and the screws do not increase the overall size of the back plate 20 and the support plate 11 in the second direction Z, and the overall thickness of the display module 100 is small.

[0069] In some embodiments, please refer to Figure 7 and Figure 8 The outer casing 10 also includes a support frame 12 connected to the edge of the support plate 11. The support frame 12 is located on the periphery of the back plate 20. The end of the support frame 12 away from the support plate 11 along the second direction Z is provided with a plurality of notches 121. A plurality of connectors are located in the corresponding notches 121 respectively. The connectors abut against the wall of the notch 121 along the second direction Z.

[0070] The support frame 12 is arranged around the support plate 11 and is fixedly connected to the edge of the support plate 11 to form a frame structure, enhancing the overall strength of the outer shell 10. The support frame 12 and the support plate 11 form a groove, within which the back plate 20 and the connectors are located. In multiple directions perpendicular to the second direction Z, the support frame 12 can protect multiple sides of the back plate 20.

[0071] The support frame 12 has multiple notches 121 at the end away from the support plate 11 along the second direction Z, that is, the notches 121 are open at the end of the support frame 12 away from the support plate 11 along the second direction Z.

[0072] Multiple connectors are located in corresponding notches 121, meaning that each notch 121 corresponds to a connector. The support frame 12 is arranged around the support plate 11, and the multiple notches 121 are distributed along the circumference of the support plate 11, which can locate the overall position of the multiple connectors on the circumference of the support plate 11, that is, locate the position of the back plate 20 on the circumference of the outer shell 10. The circumference of the support plate 11 is perpendicular to the second direction Z.

[0073] The connector is located in the notch 121 and the connector is located in the groove, so the notch 121 communicates with the groove. The notch 121 is open on the inner surface of the support frame 12. The inner surface of the support frame 12 refers to the surface of the support frame 12 facing the back plate 20 in the direction perpendicular to the second direction Z.

[0074] The connector abuts against the wall of the notch 121 along the second direction Z. That is, the head of the screw abuts the connector against the wall of the notch 121 near the end of the support plate 11 along the second direction Z. The wall of the notch 121 can position the overall position of multiple connectors relative to the support frame 12 in the second direction Z, that is, position the back plate 20 relative to the outer shell 10 in the second direction Z.

[0075] When the back plate 20 is connected to the support plate 11, multiple connectors are inserted from one end of the support frame 12 away from the layer in the second direction Z into the corresponding notch 121. Then, screws are used to pass through the connecting hole 44 and connect to the support plate 11 from the side of the connector away from the support plate 11 in the second direction Z. The head of the screw holds the connector against the wall of the notch 121 in the second direction Z.

[0076] The beneficial effects of this embodiment are as follows: Since the support frame 12 is located on the periphery of the back plate 20, the support frame 12 can protect the back plate 20 from multiple sides in multiple directions perpendicular to the second direction Z. Multiple notches 121 on the support frame 12 correspond one-to-one with multiple connectors, enabling the overall position of the multiple connectors in the circumferential direction of the support plate 11, that is, positioning the back plate 20 in the circumferential direction of the outer shell 10. The connectors abut against the walls of the notches 121 along the second direction Z, enabling the overall position of the multiple connectors relative to the support frame 12 in the second direction Z, that is, positioning the back plate 20 relative to the outer shell 10 in the second direction Z, allowing the back plate 20 to be quickly connected to a designated position on the outer shell 10.

[0077] In some embodiments, please refer to Figure 7 and Figure 8 The first connecting structure 30 includes an elastic arm, a second hook, and a screw; the second connecting structure 40 includes a connecting part 43, a first hook 45, and a connector.

[0078] The connecting part 43 and the first hook 45 are located between the back plate 20 and the support plate 11. The first hook 45 is connected to the back plate 20 through the connecting part 43. The first hook 45 is connected to the end of the connecting part 43 away from the back plate 20 along the second direction Z. The end of the first hook 45 away from the connecting part 43 along the first direction X has a first limiting wall 41. The end of the first hook 45 close to the back plate 20 along the second direction Z has a second limiting wall 42. The elastic arm is the first limiting part 31, and the second hook is the second limiting part 32. The elastic arm is connected between the support plate 11 and the second hook. The second hook engages with the first hook 45. The second hook is located between the first hook 45 and the back plate 20 along the second direction Z.

[0079] The connector has a connecting hole 44 extending along the second direction Z, which penetrates the connector along the second direction Z. The wall of the connecting hole 44 is a first limiting wall 41, and the end of the connector away from the support plate 11 along the second direction Z has a second limiting wall 42. A screw passes through the connecting hole 44 and is connected to the support plate 11. The shank of the screw is a first limiting part 31, and the head of the screw is a second limiting part 32. The head of the screw abuts against the second limiting wall 42.

[0080] In some embodiments, please refer to Figure 7 and Figure 8 The edge of the back plate 20 can be glued and fixed to the support frame 12. When the back plate 20 is under pressure, the support frame 12 can restrict the edge of the back plate 20 from moving closer to the center of the back plate 20, thereby reducing the deformation of the back plate 20.

[0081] In some embodiments, please refer to Figure 7 and Figure 8 The first direction X is the length direction of the display module 100, and at least two first connecting structures 30 spaced along the first direction X are located on both sides of the center of the support plate 11; at least two second connecting structures 40 spaced along the first direction X are located on both sides of the center of the back plate 20.

[0082] The back plate 20 has a large size and low bending stiffness in the length direction of the display module 100. The center position of the back plate 20 has low strength and is easy to deform. At least two first connecting structures 30 are located on both sides of the center position of the support plate 11 along the length direction of the display module 100, and at least two second connecting structures 40 are located on both sides of the center position of the back plate 20 along the length direction of the display module 100.

[0083] When the center of the back panel 20 is compressed by the support plate 11, it may deform along the second direction Z towards the display panel 60. Other parts of the back panel 20 on both sides of the center along the first direction X move closer to the center of the back panel 20. The second connecting structures 40 located on both sides of the center of the back panel 20 along the first direction X also move closer to the center of the back panel 20. The two spaced first connecting structures 30 abut against the two second connecting structures 40, restricting the two second connecting structures 40 from moving closer to the center of the back panel 20, thereby hindering the deformation of the center of the back panel 20 and reducing the amount of deformation at the center of the back panel 20.

[0084] In some embodiments, please refer to Figure 5 and Figure 6 Multiple first connecting structures 30 are distributed around the center of the back plate 20 by their orthogonal projections along the second direction Z on the back plate 20, and multiple second connecting structures 40 are distributed around the center of the back plate 20; the multiple first connecting structures 30 are used to abut and constrain the corresponding second connecting structures 40 in a direction perpendicular to the second direction Z.

[0085] The direction perpendicular to the second direction Z also includes other directions that intersect with the first direction X. Multiple first connecting structures 30 are used to abut and constrain the corresponding second connecting structure 40 in the direction perpendicular to the second direction Z. That is, in other directions perpendicular to the second direction Z and intersecting with the first direction X, the first connecting structure 30 can also abut and constrain the corresponding second connecting structure 40, limiting the second connecting structure 40 to approach the center of the back plate 20.

[0086] When the center of the back plate 20 is pressed by the support plate 11, it may deform along the second direction Z towards the display panel 60. Other parts of the back plate 20 around the center of the back plate 20 move closer to the center of the back plate 20, and multiple second connecting structures 40 around the center of the back plate 20 also move closer to the center of the back plate 20. Multiple first connecting structures 30 are used to abut and constrain the corresponding second connecting structures 40 in the direction perpendicular to the second direction Z. Therefore, in the direction perpendicular to the second direction Z, multiple first connecting structures 30 can limit the multiple second connecting structures 40 from moving closer to the center of the back plate 20, thereby hindering the deformation of the center of the back plate 20 and reducing the amount of deformation at the center of the back plate 20.

[0087] The resultant force of the supporting force of the multiple first connecting structures 30 on the second connecting structure 40 is opposite to the pressure of the support plate 11 on the center of the back plate 20. Increasing the number of first connecting structures 30 and second connecting structures 40 can increase the resultant force of the supporting force of the first connecting structures 30 on the second connecting structure 40, thereby reducing the deformation of the back plate 20.

[0088] In some embodiments, please refer to Figure 2 and Figure 3The second connecting structure 40 is located between the edge of the back plate 20 and the center of the back plate 20, and the orthographic projection of the first connecting structure 30 along the second direction Z on the back plate 20 is located between the edge of the back plate 20 and the center of the back plate 20.

[0089] When the center of the back plate 20 deforms, compared with the second connecting structure 40 being located at the edge of the back plate 20, if the second connecting structure 40 is located between the edge of the back plate 20 and the center of the back plate 20, the angle between the direction of the supporting force of the first connecting structure 30 on the second connecting structure 40 and the opposite direction of the pressure of the support plate 11 on the center of the back plate 20 is smaller. In the opposite direction of the pressure of the support plate 11 on the back plate 20, the component of the supporting force of the first connecting structure 30 on the second connecting structure 40 is larger, which can reduce the amount of deformation at the center of the back plate 20 to a greater extent.

[0090] In some embodiments, please refer to Figure 2 The backlight assembly 50 is located on the side of the back plate 20 along the second direction Z close to the display panel 60. The edge of the back plate 20 is bent away from the support plate 11, which can protect the backlight assembly 50 and also improve the strength of the edge of the back plate 20.

[0091] The display module 100 also includes a frame 80, a first light-shielding tape 91, a second light-shielding tape 92, and two polarizers 70. The frame 80 is connected to the edge of the back panel 20 and between the back panel 20 and the display panel 60. The display panel 60 is connected to the end of the frame 80 away from the back panel 20 along the second direction Z. The frame 80 can support the display panel 60. The first light-shielding tape 91 extends along the edge of the display panel 60 and is located at the end of the display panel 60 near the backlight assembly 50 along the first direction X, which can prevent light leakage from the backlight assembly 50. The second light-shielding tape 92 extends along the edge of the display module 100, covering the side of the display module 100. The second light-shielding tape 92 extends from the side of the display module 100 to the side of the display panel 60 away from the frame 80 along the second direction Z. The second light-shielding tape 92 also extends from the side of the display module 100 to the side of the support plate 11 away from the back plate 20 along the second direction Z, preventing light leakage from the display panel 60. Two polarizers 70 are respectively disposed on both sides of the display panel 60 along the second direction Z. The polarizer 70 located between the display panel 60 and the backlight assembly 50 can convert the light from the backlight assembly 50 into linearly polarized light. The other polarizer 70 can resolve the polarized light modulated by the display panel 60, realizing an image visible to the human eye.

[0092] In some embodiments, please refer to Figures 2 to 6The display module 100 of this application embodiment includes a housing 10, a back plate 20, a display panel 60, and a backlight assembly 50. The housing 10 has a support plate 11, which has at least two first connecting structures 30 spaced apart along a first direction X. The back plate 20 is located on one side of the support plate 11 along a second direction Z, which is perpendicular to the first direction X. At least two second connecting structures 40 spaced apart along the first direction X are provided on the back plate 20, and each of the multiple second connecting structures 40 is connected to a multiple of the first connecting structures 30 in a one-to-one correspondence. The at least two spaced first connecting structures 30 are used to abut and constrain the corresponding second connecting structures 40 in the first direction X. The display panel 60 is connected to the back plate 20 and is located on the side of the backlight assembly 50 away from the back plate 20 along the second direction Z. The backlight assembly 50 is connected to the back plate 20 and is used to illuminate the display panel 60.

[0093] Multiple first connecting structures 30 are distributed around the center of the back plate 20 by their orthogonal projections along the second direction Z on the back plate 20, and multiple second connecting structures 40 are distributed around the center of the back plate 20; the multiple first connecting structures 30 are used to abut and constrain the corresponding second connecting structures 40 in a direction perpendicular to the second direction Z.

[0094] The second connecting structure 40 has a first limiting wall 41 and a second limiting wall 42. The first limiting wall 41 intersects with the first direction X, and the second limiting wall 42 intersects with the second direction Z. The first connecting structure 30 includes a first limiting part 31 and a second limiting part 32. The first limiting part 31 is connected to the support plate 11, and the second limiting part 32 is connected to the first limiting part 31. At least two spaced first limiting parts 31 are used to abut against and constrain the two spaced first limiting walls 41 in the first direction X; the second limiting parts 32 are used to abut against and constrain the second limiting wall 42 in the second direction Z.
